近年来,节约能源成了社会的共识。收集零碎能量(人流、车流、振动发电、微风力发电、微型太阳能光伏电、踏板发电等)不但能大大节省能源,而且可以让我们的生活变得更安全、舒适。将收集到的零碎电给家庭弱电器直接供电,当电流、电压低于限定时,台灯不亮了,电脑不工作了,这时将电线插头拔下来,再插到交流电源插座,就太麻烦了。因此,零碎电能与交流电自动切换就是一个新问题。较为理想的应该是,平时以收集到的零碎电工作为主,当电压、电流低了,交流电就自动启动工作;反之,当零碎电达到工作值时,又自动切换到用零碎电工作。这其中“自动切换”是一
In recent years, energy conservation has become the consensus of society. Collecting energy (people flow, traffic flow, vibration power generation, wind power generation, micro solar photovoltaic power generation, pedal power generation, etc.) can not only save energy, but also make our life more secure and comfortable. When the current and voltage are lower than the limit, the lamp does not light and the computer does not work. At this time, it is too troublesome to unplug the power cord and then plug it into the AC power outlet It’s Therefore, the automatic switching of fractional power and AC power is a new issue. Ideally, it is usually collected by the fractional electrician as the main, when the voltage and current is low, the AC automatically start work; the other hand, when the piecemeal electricity to work value, it automatically switches to work with the piecemeal electricity. This one “auto switch” is one
